# FS QA Test 535
#
# This testcase is trying to test recovery flow of generic filesystem,
# w/ below steps, once i_mode changes, after we fsync that file, we can
# expect that i_mode can be recovered after sudden power-cuts.
# 1. touch testfile or mkdir testdir
# 2. chmod 777 testfile/testdir
# 3. sync
# 4. chmod 755 testfile/testdir
# 5. fsync testfile/testdir
# 6. record last i_mode
# 7. flakey drop
# 8. remount
# 9. check i_mode
#
